SHIELD OR HOOP FOR SPOOLS OR BOBBINS.

SPECIFICATION forming part of Letters Patent No. 745,948, dated December 1, 1903.

Application iiled March 24, 1903. Serial No. 149,393. (No model.)

To @ZZ whom t may concern.-

Beit known that I, WALTER BENNETT WIL- SON, residing at Barnsley, in the county of York, England, have invented certain new and useful Improvements in Shields or Hoops for Spools or Bobbins; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in shields, hoops, or ferrules, hereinafter referred to as hoops,for application to spools, bobbins, and the like; and it consists of a hoop having an internal waved or curved edge which is to be inserted into the end or flange of the spool or bobbin, while the outer portion of the hoop incloses and protects the exterior of the end of the tube, being secured against lengthwise movement thereon by being milled or creased or its edge folded and turned or pressed into or onto the exterior of the bobbiu or spool. The waved or curved lock-fast edge being forced into the end of the spool or bobbin eectually prevents its turning round thereon, and the improved hoop is thus securely locked fast.

Referring to the drawings,which form a part of this specication, Figure l is a plan view of the improved hoop, showing the inside of same. Fig. 2 is a section on line A B of Fig. l. Fig. 3 is a plan view of the improved hoop, showing the outside of same. Fig. 4 is a cross-section of the lower portion of a slubbing-bobbin with its end prepared for the reception of the improved hoop. Fig. 5 is a cross-section on line C D of Fig. 6, showing the hoop applied. Fig. 6 is a plan view, partly in section, of the under side of the bobbin with the hoop applied.

The improved hoop is clearly illustrated by the accompanying drawings, and its application to various forms of spools, bobbins, or the like is hereinafter described. The hoop is pressed or stamped from a disk or ring of sheet metal in such amanner that the inner edge l is in the form of a waved or curved line turned upward like the letter L in crosssection, (see Fig. 2,) and the outer portion 2 is as ordinary.

The hoop is applied to the bobbiu or spool by being passed into the end of the latter and the edge l pressed into the end thereof or into a groove, such as K, formed for its reception. Before the hoop is applied to the spool or bobbin the latter may be provided with the groove, such as K, and the corner or edge 5 is turned down or set back to receive the corner of the hoop, though the grooving is not necessary in the case of bobbins or spools made of soft wood, as the waved edge l will make its own recess by being pressed into the wood. When the hoop is applied as described, the outer edge 3 is creased or turned over the shoulder of the bobbin or spool.

It will be seen on reference to the drawings that the waved or curved edge l constitutes, practically, a hoop having several different diameters l 2 3, and these effectually prevent the hoop when applied turning round on the bobbin or spool, and the turned-over edge 3 preventing endwise movement the hoop is securely fixed in position.

Having now described my invention, what I claim is new, and desire to secure by Letters Patent, is-

The combination, with a' spool or bobbin having an annular corrugated groove in one end thereof, the bottom of the said groove being serrated, of a reinforcing-ferrule encircling the end portion of the said spool or bobbin and having an upturned corrugated flange provided with a serrated edge which engages with the corrugated sides and the serrated bottom of the said groove.

In testimony whereof I affix my signature in presence of two witnesses.

WALTER BENNETT WILSON.
